I actually prefered the "sleeve case" mount for this printer, but it wouldn't fit my cpu cooler and the GPIO pins I use.
So I remixed satanasinc's design, added the mount bars from the sleeve case which use the vertical screws already installed on the printer and I removed the old screw holder.
I also cut out the cover so that you don't need to remove the GPIO cables or accidently pull them when opening it. It's not cut out perfectly since this was one of my first 3D projects but it's working.
You can also still use satanasinc's lid designs if you want to, since the dimensions didn't change.
